摘要
本文介绍了我国水土流失状况和坡地苎麻防治水土流失的良好效果;从苎麻根系发达、覆盖度高、抗逆性强等方面阐明了苎麻保持水土的原因,并从成本低、见效快、缓解天然纤维与粮争地的矛盾、比较效益明显等方面分析了利用苎麻保持水土的优势。
In this article, the condition of soil erosion in China and the effective result of the prevention of water and soil erosion by planting ramie on the slope land were described. The reason that ramie conservated soil and water was clarified from the following characteristics of ramie： well-developed root system, covering high, strong resistance and so on. The advantage of soil and water conservation by using ramie was analyzed from the following aspects：low cost, quick results, relieving contradiction on contention of the land between natural fiber and food crops, obvious comparing benefits and so on.
